I just made the change from g++ 1.32 to g++ 1.35.1. I'm discovering that g++ 1.32 was very permissive. For example, 1.32 compiled stuff similar to the following, where as 1.35.1 complains: class Picture : public Graphic { public: int GraphicsContaining(Graphic**&); // other stuff }; class Selection : public Picture { // other stuff }; class PictSelection : public Selection { // right stuff }; inline int PictSelection::SelectionsContaining(Selection**& ss) { return Picture::GraphicsContaining(ss); } G++ 1.35.1 says: bad argument for function `Picture::GraphicsContaining (struct Graphic **&)' (type was struct Selection **) Don't tell me that I have to cast. Selection is a derived from Graphic. Say it aint so. Rich Johns, MCC CAD Program | 3500 W.
